Help!

Hi, I love this site. I have a question. I will have my 5th remicade infusion on Tuesday, however I have had some bloody bowel movements not many, maybe 1 per day 3 bowel movements a day total about a week ago. I saw my nutritionists this week and she put me on a gluten free diet. She also gave me acidophilis 4 pills per day. My stomach cramps and I have watery diarrhea 4-6 times a day. No bleeding (thank God). Should I contact the gastro doctor before my next remicade infusion.
